CYCLIZATION OF NITRILES. X. ENAMINO NITRILES OF THE 1,3-DITHIA-4-CYCLOHEXENE SERIES AND THEIR RECYCLIZATION TO DERIVATIVES OF PYRIDINE AND THIAZOLE

The recyclization of 4-amino-6-aryl-5-cyano-2-cyclopentane(cyclohexane)spiro-1,3-dithia-4-cyclohexenes, obtained from gem-dithiols and arylidenemalononitriles, leads to the formation of 4-aryl-5,6-polymethylene-3-cyano-2-(1H)-pyridinethiones.The latter are used in the synthesis of various 3-aminothienopyridines, 4-aryl-3-amino-5,6,7,8-tetrahydrothienoquinolines, and other heterocyclic compounds condensed with quinoline. 1-Cyano-1-(4-aryl-2-thiazolyl)-2-arylethylenes were obtained by the reaction of the 1,3-dithia-4-cyclohexenes with phenacyl bromides.
